Ecological restoration method of dewatered sludge landfill and application of landscaping clip waste

Abstract

The invention provides an ecological restoration method of a dewatered sludge landfill and application of landscaping clip waste. The landscaping clip waste is utilized for being laid in drainage blind ditches and improving soil, the gas permeability capacity and permeable capacity of the soil are improved, and soil organic matter is increased; the problem is solved that due to the fact that the soil of the dewatered sludge landfill is poor in water penetration and drainage performance, a large number of planted nursery stocks die, the survival rate of transplanting the nursery stocks is increased, in the later period, various nursery stocks grow well, flowering arbors and shrubs, ornamental foliage arbors and shrubs, and arbors and shrubs with ornamental fruits, flowers and plants flourish, all the flowers bloom together, characteristics of natural growth are sufficiently shown, and a good ecological restoration effect is achieved.

Description

technical field [0001] The invention relates to the technical field of ecological restoration, in particular to the application and restoration method of landscaping pruning waste in the ecological restoration of dewatered sludge landfills. Background technique [0002] Municipal sludge is a solid-containing liquid with extremely high water content formed in the process of sewage treatment, and its volume can reach several times the volume of the solid contained in it. With the continuous acceleration of China's urbanization process, the sewage sludge in urban pipe networks, rivers and lakes is increasing. According to statistics, by the end of September 2013, the national output of urban sludge (water content less than 80%) has reached 30 million t / d, and the output of sludge will increase year by year at 2.5 million t / d. Due to the characteristics of high water content, large volume, easy corruption, and foul smell, the sludge from urban sewage treatment plants is mainly ...

Problems solved by technology

However, during the reconstruction process, due to the poor soil water seepage and drainage performance of the dewatered sludge landfill site, a large number of planted seedlings died. Therefore, after years of practice and continuous in-depth research, we have worked out a set of ecological conditions for the dewatered sludge landfill site. An energy-saving and environment-friendly method that can improve the survival rate of seedling transplanting during restoration
